One way to picture pastiche: a pie with borrowed fillings stirred into it. You can still taste where each filling came from, and that is the whole point, because the maker wants the borrowing noticed. Sometimes the pie carries just one borrowed flavour, and that is work made in another artist's style. Sometimes several are stirred in at once. Stirred well, it is a skill; stirred badly, it is just scraps in a crust.
From the word’s history
Wiktionary traces pastiche through French pastiche to Italian pasticcio, glossed as pie, something blended, and further back to Late Latin pasta, dough or paste. The food picture is the older one; the art meaning is built on top of it.
Wiktionary 記錄的路線是：法文 pastiche 來自義大利文 pasticcio（派、混在一起的東西），再往上是晚期拉丁文 pasta（麵團）。也就是說，食物的畫面在前，藝術上的意思是後來蓋在上面的。
